Upon learning that its elusive and longtime adversary is dead, Kabul is taking steps to ensure that Afghans don't mourn the loss of Mullah Mohammad Omar.

Security forces were ordered by the government on August 3 to prevent citizens from publicly grieving over the Taliban leader's death, and were reminded by National Directorate of Security (NDS) spokesman Haseeb Siddiqui that Mullah Omar was "the biggest cause of war and backwardness in the modern history of Afghanistan."

Siddiqui said that any ceremony held in Mullah Omar's honor would be seen as an "insult" to his thousands of victims and would be considered a "legitimate" target for security forces to attack.

According to the province's deputy governor, Mohammad Ali Ahmadi, five Taliban fighters were killed and several others injured during the raid.

In the wake of Mullah Omar's 2013 death, which was confirmed last week, Taliban spokesman Zabihullah Mujahid has said that dozens of gatherings have taken place across Afghanistan to both remember Mullah Omar and to express support for his stated successor, Mullah Akhtar Mansur.

Supporters of the extremist group have also reportedly offered funeral prayers for their late leader at mosques in Islamabad and other Pakistani cities, including Karachi and Lahore.

Afghan media, however, have reported that the Taliban has been forcing local residents to attend mourning ceremonies by setting up roadblocks and ordering commuters to go.

Meanwhile, thousands of Afghans took to the streets to condemn Mullah Omar and denounce vows by his successor to continue fighting in Afghanistan.

In Parwan Province, north of Kabul, a large-scale anti-Taliban rally reportedly took place on August 4, according to RFE/RL's Radio Free Afghanistan.

"Many people from the provincial capital, Chari Kar, and other districts are attending the rally, and they denounce any funerals held for Mullah Omar, saying such funerals would give legitimacy to the Taliban militancy," RFE/RL correspondent Ahmad Hanaesh reported from Parwan.

Authorities have stepped up security over the past two days to prevent any violence, as the atmosphere is "highly charged," the correspondent said.

An anti-Taliban rally was also held in central Bamiyan Province, where the Taliban infamously demolished two ancient giant Buddha statues in 2001 and have long targeted members of the province's Shi'ite Hazara minority.

The August 4 rally -- led by Bamiyan's civil activists, local religious council leaders, and former mujahedin -- said any commemoration or tribute was "unjustifiable" and "unacceptable."
